Because using cleanup may unexpectedly clobber the variables you want
to keep.  When using

for var in [..]:
  ..
del var

idiom, I tend to maintain some naming convention for what var can be
so that it does not conflict with other global variables.  Naming
conventions are usually considered suboptimal work-arounds for
languages with poor namespace support.
